Patented June v 2, -1942 UNITED STATES PATENT ()FFICE l 2,284,933 TYPING APPARATUS v Ransom H. Turner, Great Neck, N. Y. Application February 3,- 1940, serial No. 317,913

(c1. lez-a1) 68 Claims.

This invention relates more particularly to improved means for preparing l,instilled type copy suitable for photographic reproduction for employment in printing processes of the litho graphic' type such as planographi'c and oiset tained in said copy are then prepared by a linecasting machine. From the type so prepared,

and al1 composed, a printed impression is made to obtain a master copy. Then, a photographic reproduction vof said master copy is made'upon a sheet or plate which is subsequently applied to a printing press for offset printing. This pracce requires the employment of. an expensive line-casting machine and the expensive services o f an operator for such a machine in order to obtain proper setwise spacing of the printed characters and justified lines. This feature of said practice contributes much to the cost of offset printing.

An important object of the present invention is to facilitate and reduce the cost of preparation of the master copy by provision of typing apparatus capable of producing typewritten master copy with properly spaced characters and justified lines and entirely suitable for direct photographic reproduction for oiset printing.

Other objects of the invention will appear hereinafter.

Fig. 37 is a central longitudinal sectional view writing machine has the usual escapement means for controlling the travel of the paper carriage of the machine in said preliminary typing. Special provision is made for controlling the travel of'the carriage for the subsequent typing of the master copy. In combination with the typewriting machine there is ai row of escapement stop elements extending along the line of carriage travel. These elements are settable varying distances apart in the series for the purpose of controlling the travel of the carriage for appropriate setwise spacing of the typed characters and for word spacing and line justication in the typing of the master copy. V Key-responsive means are provided for such setting of the vstop elements, and the setting is accomplished in said preliminary typing. Operation of the characterkeys in the preliminary typing causes accurate setting of the stop elements varying distances apart in ac- Icordance with setwise spacing appropriate to the different characters typed. At the conclusion of the preliminary typing a line-justifying key is operated and means responsive to operation of said key causes setting of the stop elements for word-spacing and line justifying. Then, in said master copy typing, a special escapement means cooperates with the set stop elements to control the travel of the carriage.

Printers type are employed upon the type heads of the typewriting machine and that, together with the accurate setwise spacing of the typed characters and the justified lines, provided for by said stop setting, enables the production of a typed master copy practically identical to a printed one obtainable from a line-cast type setup. Such a typed copy will be suitable in every way for photo-offset reproduction. The apparatus may also be employed satisfactorily for typing the master copy directly upon a sheet or plate to be applied to a press cylinder for ofl'set printing, as in a known process.

The mechanism of the typewriter machine may be in general similar to that of any one of a number of well-known makes. In the present instance the mechanismis that of a standard Underwood typewriter. It has letter keys I, figure keys 2, right and left hand case shift keys 3 and a space bar 4. Certain of the keys also bear the usual punctuation marks and symbols. The letter keys and figure keys are on levers 5 fulcrumed upon a cross bar 6 borne by the main frame and are operatively connected by sub-levers 'I to type bars 8. A carriage 8 bearing the platen III is mounted upon a rear bar I I and an under bar I2 for travel Acrosswse of the machine. Bar II supports the carriage for case shift rocking and bar I2 is supof several adjacent ones of the wedges and associated stop elements;

ported by a rocker I3 for rocking about a shaft I4, borne by the main frame of the machineto shift the carriage between upper and lower case positions. I'he case shift keys are on levers I5 fulcrumed on the cross bar 6 and each has an upwardly extending arm I6 engageable with the rocker I3 to cause shift of the platen to upper case position when either case shift key is pressed.

through the upper portion of the justifying mechanism, parts being in elevation, parts broken away and parts omitted.

Rotation of the escapement wheel for advance of the carriage in the said preliminary typing is'controlled by the escapement dogs 20 which are rockably mounted at a fixed point, asv
